Catalog API entities Working with change sets Working with the Details attribute (Legacy)Using DescribeEntity to get information about your entities

Using the AWS Marketplace Catalog API

The AWS Marketplace Catalog API service provides an API interface to manage AWS Marketplace for your AWS organization or AWS account. For approved sellers, you can manage your products programmatically, including the self-service publishing capabilities on the AWS Marketplace Management Portal. For private marketplace administrators, you can manage your private marketplace programmatically.

With Catalog API actions, you can view and update your existing product programmatically. You can automate your product update process by integrating the AWS Marketplace Catalog API with your AWS Marketplace product build or deployment pipelines. You can also create your own applications on top of the Catalog API to manage your products in AWS Marketplace. You can manage the products that users in your AWS account or AWS organization can see and purchase through your private marketplace.

The AWS Marketplace Catalog API service provides standard AWS API functionality. You can directly use the REST API actions described in Actions, or you can use an AWS SDK to access an API that's tailored to the programming language or platform that you're using. For more information about AWS application development, see Getting Started with AWS. For more information about using AWS SDKs, see AWS SDKs.

Catalog API entities

AWS Marketplace entities are containers of data which serve different business purposes, such as a product or offer. Entities are categorized by types. Each entity type encapsulates data related to a specific business domain (for example, a product or a seller account).

To simplify this paradigm, entities are designed with some level of commonality in their structures. As a result, introducing a new business domain doesn't require that you learn a completely new structure.

General structure

The general structure of any entity is:

A named type with a version
An identifier for the specific instance of the type
One or more facets that include the attributes of the entity

Type versioning

Every named type has a type and version associated with it, for example, EntityProduct@1.0. The type (EntityProduct) represents the classification of the content. The version (1.0) represents the structure of EntityProduct.

The version gives you details about the structure of the entity. The following describes when a version will be changed:

Existing entities won't be restructured without changing the version. Additions of optional new fields will result in a minor version update.
Any feature that fundamentally changes the structure of a type leads to a major version update. Examples include:
- Removing a field
- Renaming a field (different name for the same semantic)
- Changing the semantic of an existing field (for example, changing the expected type)
A major version update can retain a subset of facets from the previous version.
Users are provided notifications and documentation for new versions.

Identifier

Each entity represents a unique thing within a business domain. To identify the unique thing, we use an identifier associating an EntityId with a RevisionId, for example, prod-ad8EXAMPLE651@3. In this example, the EntityId is prod-ad8EXAMPLE651 and the RevisionId is 3. Every successful change request to the entity will update the revision.

The following are important details about the identifier:

Each entity is uniquely identified by its EntityId, which is the key to globally distinguish one entity from another.
Each published revision of an entity has a RevisionId. The RevisionId, along with the EntityId, distinguish one published revision from another.
AWS Marketplace generates EntityIds and RevisionIds.

You can use the DescribeEntity action to find the details and the Identifier with the most recent revisionId.

The RevisionId is an optional part of requests to StartChangeSet (see Working with change sets). If you include a RevisionId, then the request to StartChangeSet will fail with a ValidationException if the RevisionId is not the latest revision of the entity. This allows you to implement optimistic locking in your application.

Note

When you include a RevisionId that is not the latest revision, the ValidationException message includes the latest RevisionId.

If you omit the RevisionId, the request is performed on the latest revision of the entity automatically.

Warning

Two requests to change the same object could result with one request overwriting the changes of the other request, as the second request rewrites data changed by the first request. Using RevisionIds in your requests prevents this issue by not allowing a change to an earlier revision to overwrite the current revision.

A facet is a logical grouping of attributes. An entity usually includes several facets which represent different aspects of the entity. The attributes within a facet have the following properties:

Each attribute has a unique name within the scope of the container it belongs to.
Attributes can be of a simple type (string, integer, or floating number).
Attributes can be of a complex type (container/structure or array).

Entity type

The entity type defines what the entity represents. An entity can be a seller product in AWS Marketplace or a private marketplace. For more information, see Working with seller products and Working with a private marketplace.

Working with change sets

When using the Catalog API, requests are created and updated through entities and completed by using change requests. Every change specifies the entity to be changed, the type of change to be performed, and details of the change. The type of change to be performed is called a ChangeType. A collection of ChangeTypes is called a ChangeSet.

There are four actions that allow you to work with change sets:

StartChangeSet – Requests a set of changes. The changes are added to a queue and processed. For more information, see Working with seller products and Working with a private marketplace.
DescribeChangeSet – Gets the details of a set of changes, including the status of the request. The statuses include:
- PREPARING – Getting ready to apply the changes.
- APPLYING – In the process of making the requested changes.
- SUCCEEDED – Request was completed successfully.
- CANCELLED – Request was canceled by the user.
- FAILED – Request was completed unsuccessfully. Further details are available in the response.
ListChangeSets – Gets a list of the change sets that are currently in process.
CancelChangeSet – Requests a change set be canceled. Changes can only be canceled while in the PREPARING status.

A typical workflow is to request a change with StartChangeSet, and then use the returned ChangeSetId to poll the DescribeChangeSet action until the change is complete.

The following is an example of the DescribeChangeSet response.


{
  "ChangeSet":
  [
    {
      "ChangeName": "myChangeName",
      "ChangeType": "UpdateInformation",
      "Details": "{  \"ProductTitle\": \"My Product Title\",  \"ShortDescription\": \"My product short description.\",  \"LongDescription\": \"My product longer description.\",  \"Sku\": \"123example456\",  \"SupportDescription\": \"Need help? Contact our experts at support@example.com\\n\\nYour purchase includes 24x7 support.\",  \"Categories\": [    \"Operating Systems\",    \"Network Infrastructure\",    \"Application Development\"  ]}",
      "DetailsDocument":
      {
        "ProductTitle": "My Product Title",
        "ShortDescription": "My product short description.",
        "LongDescription": "My product longer description.",
        "Sku": "123example456",
        "SupportDescription": "Need help? Contact our experts at support@example.com\n\nYour purchase includes 24x7 support.",
        "Categories":
        [
          "Operating Systems",
          "Network Infrastructure",
          "Application Development"
        ]
      },
      "Entity":
      {
        "Identifier": "example1-abcd-1234-5ef6-7890abcdef12",
        "Type": "AmiProduct@1.0"
      },
      "ErrorDetailList":
      []
    }
  ],
  "ChangeSetArn": "arn:aws:aws-marketplace:[exampleARN]",
  "ChangeSetId": "example123456789012abcdef",
  "ChangeSetName": "myChangeSetName",
  "EndTime": "2023-03-03T00:00:00Z",
  "FailureCode": null,
  "FailureDescription": null,
  "StartTime": "2023-03-02T00:00:00Z",
  "Status": "SUCCEEDED"
}

Note

When polling or working with change sets programmatically, you must adhere to the service limits. For more information, see Service quotas for AWS Marketplace Catalog API.

After your change is complete, you can use ListEntities to find the entity that you created or modified (and its associated EntityID). You can then use DescribeEntity with the EntityID to get details about it.

For more information about working with change requests in the console for sellers, see Creating a change request in the AWS Marketplace Seller Guide.

Making multiple change requests simultaneously

Within a single change set, you can bundle all change types and they are run together. Catalog API is built to make multiple changes simultaneously to provide the best performance. Sellers and Channel Partners can invoke changes with multiple ChangeTypes bundled into a ChangeSet. You can invoke multiple changes on single or different entities in the same ChangeSet. Catalog API evaluates which order the changes need to be applied and makes those changes.

However, if the requests are made as separate change sets, AWS Marketplace can't initiate conflicting change requests on the same product. In these cases, AWS Marketplace returns a ResourceInUseException error.

For modifying AMI and container products, most changes can be made without error, with the following exceptions:
- If two requests are the same ChangeType on the same product, the second request returns an error.
- If one request is to update the version information, and the other request is to restrict or add a version, then the second request returns an error.
- If a request is PREPARING, another request can be made on the same product. However, a change that is currently APPLYING may block other requests, returning an error.
For other product types and private marketplaces, you can only have a single request for a product at a time. If a different request to update the same product is made while a first request is ongoing, the second returns an error.
If there is a request for any product that is pending with the AWS Marketplace Seller Operations team, then any other requests on that product return an error.

If you receive a ResourceInUseException error for a change request, you can retry the request later. Depending on the state of the ongoing request, you can also cancel the first request, to allow the resubmitted second request to complete sooner.

Invoking multiple change types in one change set

You can use the Catalog API to combine and chain up to 20 changes in one StartChangeSet request targeting one or multiple different entities.

A typical use case is to create a SaaSProduct@1.0 draft product, an Offer@1.0 draft offer, and also filling in the metadata information of the product and offer. This is done by including the following four change types in one change set:

CreateProduct on SaaSProduct@1.0

Specify the ChangeName parameter. Then, the product created in this change type can be referenced in the same change set by subsequent changes.

For example, CreateProductChange.
UpdateInformation on the SaaSProduct@1.0 created in the same change set

In the Entity.Identifier field, you can refer to the product created by CreateProduct change type using the change name in this format:

${ChangeName}.Entity.Identifier

For example, $CreateProductChange.Entity.Identifier.
CreateOffer on Offer@1.0 tied to the SaaSProduct@1.0 created in the same change set

Specify the ChangeName parameter. Then, the product created in this change type can be referenced in the same change set by subsequent changes. For example, CreateOfferChange.

For the ProductId parameter in the payload of CreateOffer change type, you can also refer to the SaaS product created in CreateProduct change type by using ${ChangeName}.Entity.Identifier syntax.

For example, {"ProductId":"$CreateProductChange.Entity.Identifier"}.
UpdateInformation on the Offer@1.0 created in the same change set

In the Entity.Identifier field, you can refer to the offer created by the CreateOffer change type using the change name in this format:

${ChangeName}.Entity.Identifier

For example, $CreateOfferChange.Entity.Identifier.

The following is an example of a combined change set.


POST /StartChangeSet HTTP/1.1
Content-type: application/json

{
  "Catalog": "AWSMarketplace",
  "ChangeSet": [
    {
      "ChangeType": "CreateProduct",
      "Entity": {

        ],
      }
    },
    {
      "ChangeType": "CreateOffer",
      "Entity": {
        "Type": "Offer@1.0"
      },
      "ChangeName": "CreateOfferChange",

      "Entity": {
        "Type": "Offer@1.0",
        "Identifier": "$CreateOfferChange.Entity.Identifier"
      },
      "DetailsDocument": {
        "Name": "Offer created together with SaaSProduct",
        "Description": "Test offer created together with SaaSProduct in the same Catalog API change set"
      }
    }
  ]
}

Working with the `Details` attribute (Legacy)

Note

This section describes the legacy Details attribute in your change request, which requires additional formatting for your change details. We recommend using the alternative DetailsDocument attribute. It doesn't require additional formatting and the change details don't need to be changed. For examples of the DetailsDocument attribute, see Working with seller products and Working with a private marketplace.

The Details attribute of the StartChangeSet operation is a string value. Its contents are JSON objects. To put a JSON object into a string attribute, you must convert the object to a single-line string by escaping all JSON control characters, and removing line breaks.

For example, if you are using the StartChangeSet operation with UpdateProcurementPolicy to disable requests from users in your private marketplace, make a request like the following.


POST /StartChangeSet HTTP/1.1
Content-type: application/json

{
   "Catalog": "AWSMarketplace",
   "ChangeSet": [ 
      { 
         "ChangeType": "UpdateProcurementPolicy",
         "Details": "<string>",
         "Entity": {
            "Type": "Experience@1.0",
            "Identifier" : "exp-1234example@5"
         }
      }
   ]
}

In this case, the JSON object that you use for the Details attribute looks like the following (before conversion to a string).


{
    "Configuration": {
        "PolicyResourceRequests": "Deny"
    }
}

But the Details attribute requires a string, not JSON. After converting this JSON object to a single line string, it looks like the following.


"{\"Configuration\" : {\"PolicyResourceRequests\" : \"Deny\"}}"

With this string, you can create the full change set request, as follows.


POST /StartChangeSet HTTP/1.1
Content-type: application/json

{
   "Catalog": "AWSMarketplace",
   "ChangeSet": [ 
      { 
         "ChangeType": "UpdateProcurementPolicy",
         "Details": "{\"Configuration\" : {\"PolicyResourceRequests\" : \"Deny\"}}",
         "Entity": {
            "Type": "Experience@1.0",
            "Identifier" : "exp-1234example@5"
         }
      }
   ]
}

Generally, examples in this API reference show the JSON object already converted to a string. In some cases, more complicated samples with new lines are included to enhance understanding.

Automate converting JSON to a string

Converting a JSON object to a string can be automated using tools such as jq, a lightweight command-line JSON processor. The following example shows using jq to convert a JSON object to a string that can be used in the Details attribute.


DETAILS_JSON='{
  "ProductTitle": "My Product Title",
  "ShortDescription": "My product short description.",
  "LongDescription": "My product long description."
}';

DETAILS_JSON_STRING="$(echo "${DETAILS_JSON}" | jq 'tostring';)";

If you echo "${DETAILS_JSON_STRING}", the result is the following string with JSON properly escaped: {\"ProductTitle\":\"My Product\",\"ShortDescription\":\"My product short description.\",\"LongDescription\":\"My product long description.\"}

Using DescribeEntity to get information about your entities

You can programmatically get information about your existing entities, including products and private marketplace, through the Catalog API.

The ListEntities action returns a list of entities. Then, you can use the DescribeEntity action to get details about an individual entity. This can be directly useful, for example, to catalog the products you sell. It can also be useful when updating entities, because you can get the current state of the entity before updating just the parts that you want to update.

The following example shows using ListEntities to get a list of container products, and then using DescribeEntity to get information about one of the specific products.


POST /ListEntities HTTP/1.1
Content-type: application/json

{
  "Catalog": "AWSMarketplace",
  "EntityType": "ContainerProduct"
}

For the entity type, you must use the entity type without the version. It returns all entities of that type (and doesn't filter on version).

Here is a sample of the response to the ListEntities action.


{
    "EntitySummaryList": [
        {
            "Name": "Container Product 1",
            "EntityType": "ContainerProduct",
            "EntityId": "example1-abcd-1234-5ef6-7890abcdef12",
            "EntityArn": "arn:aws:aws-marketplace:[exampleARN]",
            "LastModifiedDate": "2021-03-01T00:00:00Z",
            "Visibility": "Public"
        },
        {
            "Name": "Container Product 2",
            "EntityType": "ContainerProduct",
            "EntityId": "example2-abcd-1234-5ef6-7890abcdef12",
            "EntityArn": "arn:aws:aws-marketplace:[exampleARN]",
            "LastModifiedDate": "2021-03-02T00:00:00Z",
            "Visibility": "Public"
        }
    ],
    "NextToken": "exampleabcdef12345..."
}

To get the details of one of these products, use the DescribeEntity action. The following example shows how to get details about the first product returned above.


GET /DescribeEntity?catalog=AWSMarketplace&entityId=example1-abcd-1234-5ef6-7890abcdef12 HTTP/1.1

The following shows the response to DescribeEntity.
